Xerophytic  plant  communities  of  the  Lower  Volga  valley

Pp. 4-29

Abstract. The review and classification of the plant communities of the classes Festucetea vaginatae Soó ex Vicherek 1972 and Artemisietea lerchianae Golub 1994 of Lower Volga Valley has been carried out. They are xerophytic plant communities according to its floristic composition and ecology. The Lower Volga Valley vegetation database was used for review and classification of the plant communities. The database was created using the computer program TURBOVEG. Now it includes 14972 relevés collected during 1924–2018 on the territory of the Lower Volga Valley. Supervised and unsupervised methods for the classification of vegetation were applied. The expert system based on the Cocktail method (Bruelheide, 2000) was used as a supervised method of classification. Cluster analysis was used as an unsupervised classification method. The new alliance Carduion uncinati and the new association Carduo uncinati–Artemisietum scopariae have been established for vegetation of fallow land on brown desert soils.

The  floristic  findings  of  invasive  and  potentially  invasive  plant  species

in  the  North-West  of  the  Republic  of  Bashkortostan

Pp. 98-106

Abstract. The Republic of Bashkortostan because of the arrangement in South Ural, on border of Europe and Asia, is characterized by intensive course of invasive processes. In the last decades also naturalization of separate invasive species in natural habitats – in floodplains of the rivers, forest edges, on coastal and boggy meadows is observed. Researches on search of new locations of alien plant species are conducted since the end of the 90th years of the XX century. The publication of "black list" of flora of the Bashkortostan Republic (Abramova, Golovanov, 2016) including 100 invasive and potentially invasive plants and the "Abstract of adventive species of the Bashkortostan Republic" (Muldashev et al., 2017) which generalized data on localities of 457 alien plant species not peculiar to the nature of Bashkortostan became result of the carried-out works. Article represents addition to earlier published data, which are received during the forwarding researches of 2018 conducted in the northwest of the Bashkortostan. The research revealed 89 new localities of 12 invasive and potentially invasive plant species: Collomia linearis, Echinocystis lobata, Erigeron annuus, Heracleum sosnowskyi, Hippophae rhamnoides, Hordeum jubatum, Impatiens glandulifera, Lepidium densiflorum, Lupinus polyphyllus, Rosa rugosa, Solidago canadensis, S. gigantea.

Pp. 114-118

Abstract. As a result of the conducted field research in the territory of the Orenburg region reed huge (Phragmites altissimus (Benth.) Mabille) was for the first time noted. Earlier this species was not fixed both in Orenburg region, and in many adjacent regions. In this location this species is, apparently, adventive, accidentally ingressed species, near borders of a natural area, which is actively settled and naturalized in natural coastal and water communities within this locality is noted. Ph. altissimus forms monodominant communities, rather big on the area, with a combination to natural coastal and water gelofits.

Demographic  characteristics  of  coenopopulations  of  Hedysarum  razoumovianum  Fisch.  et  Helm  (Fabaceae)  in  the  conditions  of  antropogenic  press (Middle  Volga  region)

Pp. 119-126

Abstract. Ontogenetic structure of natural populations of rare plant species is the main characteristic in assessing their current state and forecasting further development. In the Middle Volga basin, the ontogenetic structure of Hedysarum razoumovianum Fisch et Helm (Fabaceae) populations was studied. The species is native to the northwestern border of the range and is included in the Red Books of the Russian Federation and Samara Region. In the course of the work, population-ontogenetic research techniques were used. The assessment of the types of populations carried out by the criterion of "delta-omega". The basic ontogenetic spectrum of coenopopulations centered with the predominance of mature generative individuals. Most coenopopulations are mature normal. Average demographic indices of coenopopulations Hedysarum razoumovianum: substitution index – 0.30; recovery index – 0.31; aging index – 0.04. The average age (∆) is 0.44, the average efficiency (ω) is 0.72. The change in the demographic parameters of Hedysarum razoumovianum coenopopulations on the Middle Volga is influenced by the degree of anthropogenic load. It was revealed that a strong anthropogenic load, like its complete absence, leads to a gradual aging of populations.

Pp. 197-214

Abstract. The work summarizes data on the distribution, biological, ecological, and population characteristics and protection of the regionally rare and protected the Bryopsida moss, Neckera pennata Hedw. in the Vologda Region. To date, the species has been recorded in 92 localities in the Region, in all the administrative districts of the Region and in 38 squares of the Atlas Florae Europaeae. A total of 48 new localities from 18 administrative districts are listed for this species, at that Neckera pennata is reported for the first time for 12 districts (Babushkinskiy, Belozerskiy, Velikoustyugskiy, Verkhovazhskiy, Kichmengsko-Gorodetskiy, Mezhdurechenskiy, Nyuksenskiy, Sokolskiy, Ust’-Kubinskiy, Ustyuzhenskiy, Kharovskiy, Chagodoshchenskiy districts). In the Vologda Region, the species occur in old mesophilic aspen and aspen-spruce forests. In addition to Populus tremula L., which is the main substrate for the moss, Neckera pennata was rarely observed on 10 more species of woody plants (Larix sibirica Ledeb., Picea abies (L.) Karst., Betula pendula Roth, Populus alba L., P. balsaminifera L., Sorbus aucuparia L., Salix caprea L., Tilia cordata Mill., Ulmus glabra Huds., U. laevis Pall.). Currently, the species is included in the Red Data Book of the Vologda Region with a 3/LC status and is protected in the region in 15 protected areas, including two federal, 12 regional and one local protected area. The main threats to the existence of the species are associated with the removal or fragmentation of old forests due to logging.

Pp. 239-252


Abstract. Communities dominated by Betula litwinowii Doluch have been studied in Teberdinsky Reserve (Karachay-Cherkessia) and the Natural Park "Upper Gunib" (Dagestan). The assessment of the grass-shrub layer for 5 groups of communities of high-altitude birch forests was carried out using the indices of Menhinik, Margalef, Shannon, Simpson, Shannon-Weaver equalization index and dominance index, reflecting different aspects of biodiversity. The comparison of the obtained indicators of equalization of the grass-shrub layer of mountain birch forests of the studied regions of the North Caucasus with the literature data was carried out. It is shown that values of indices of Margalef and Menhinick exhibit greater scatter of the average values. With high species richness, Simpson and Shannon indices have medium-high values. Indices are determined, which enable to estimate the level of biodiversity in mountain birch communities most objectively, and allow to comparing syntaxons of these communities.

Synopsis of alien plants of the Middle Volga Region

Pp. 353-396


Abstract. For the first time, a list of alien plants registered on the territory of the Middle Volga Region (within the boundaries of Samara and Ulyanovsk Regions) is published. The alien flora of the Middle Volga Region is represented by 461 species of vascular plants belonging to 275 genera and 77 families (23.1% of the total flora). For each species information is provided about the time of occurrence in the flora (archaeophyte, neophyte), mode of introduction (xenophyte, ergasiophygophyte), invasive status (ephemerophyte, colonophyte, epecophyte, agriophyte), life form, geographical element, frequency of occurrence, range of occupied habitats, as well as the date of first mention. The predominance of neophytes (394 species, 85.5%) over archaeophytes (67 species, 14.5%) was found in the alien flora of the Middle Volga region. For the first time, information is provided on the findings of such species as Cleome spinosa, Echinacea purpurea, Grindelia squarrosa, Jovibarba globifera, Phaseolus vulgaris, and Rudbeckia laciniata. All listed species are accompanied by comments. Among alien plants is dominated by epecophytes (149 species, 32.3%) and ephemerophytes (148 species, 32.1%), 142 species are colonophytes (30.8%) and 22 (4.8%) are agriophytes. 21 species belong to the disappeared ones, they are listed in the general list, but are not included in the analysis. Currently, there is a high rate of adventization of the regional flora – 161 species (35.0% of their total number) recorded in the last 20 years. According to the modes of introduction, alien species are distributed almost equally – 227 xenophytes (49.2%) and 234 ergasiophygophytes (50.8%). The most common alien species in the region have been identified. The results of distribution of alien species are presented by habitat types.
